Good Value
Works well for the price point. Would recommend checking shaft tolerance before ordering.
Description
This is a 3-jaw type elastic torque coupling designed to connect motor shafts in air compressor systems. Constructed from 45# steel, the unit features a star or plum-shaped elastomeric insert that absorbs vibration and compensates for minor shaft misalignment during operation. The XL series designation indicates specific dimensional standards suitable for medium-duty mechanical power transmission applications. Ensure the spider insert is properly seated between the jaws before tightening fasteners to maintain balanced torque transfer.

Quiet Operation
Much quieter than the old coupling. The elastic element absorbs shock well.
